Audio playback from within a state machine without halting execution

[wshato]

I have created a state machine that acquires and analyzes an input signal and transitions states based on triggers detected within that signal.  In one particular state I need to play back a prerecorded file (right now I am just using a .wav file for testing purposes).  I understand that due to the data flow model the state machine hangs up during the playback state until the playback is finished, but I need to find someway around this.  Obviously, whenever the machine hangs up it cannot continue acquiring and analyzing the signal.  How can I start the playback from within the state machine without halting its execution?

Do you use the sound output VIs? If you do, try this. On the "Play Sound File VI" set the timeout value=0

Thank you.  I was not using that particular vi.  I switched and now everything works perfectly.  Greatly appreciated.
